Let's see where do I start?There are so many things discussed.I'll pick two.
First of all I have two Aresties.One with a TT60bb,the other powered by a YS63.Both planes are amazing.The two stroke will do,and has been clocked at 119mph!!(clocked even faster with a TH61bb)The four stroke powered version is for practicing pattern(fits in the car with baby seat and golf clubs).The flight characteristics of both planes are great.These planes fly where you put them.
Balancing is crucial,both ways!!
Sorry to hear about the problems!I know it's been said but keep complaining.If you spend your money,you should get a good product.Period!!!
But you did the right thing by telling people about your problems on this forum,word gets around fast here.I'm sure hanger9Aresti sales where affected!Sometimes one bad incidence and people will take there moey elsewhere!
About the planes flying without adjustments or modifications.If you buy all the same servos,motor and recommended equipment,Maybe!!But start switching up motors.You need to make sure your plane is balanced . Well!!!But the plane falling apart is inexcusible!!
